So, I just downloaded the trial version of photoshop CS5 and its currently running the 64 bit version. I want to be able to make gifs so I need the 32 bit version. I've been scrolling through the forum and it seems that the soln given doesn't work since I have the trial version. Any idea how I can get the 32 bit version during my trial period?

Really? Can you please explain how? Because when I tried to get started, this is what it was showing me: "Import Video Frames To Layers is not available in the 64 bit version of Photoshop. Please use the 32 bit version instead."

This is still not working for me. I'm running CS5.1 on a mac OSX 10.7.5. I've clicked the 32-bit checkbox, on the app icon itself, not the folder...then I go to File>Import>Video Frames to Layers and still get the pop-up: Import Video Frames To Layers is not available in the 64 bit version of Photoshop. Please use the 32 bit version instead.

I have clicked on the application and get info but it does not give me an option for clicking on anything. It just shows a box for shared folder and under that is another box that says Locked but it isn't highlighted and you can't check it.
